Distillation and Extraction

The thermal separation techniques of distillation and extraction are required in the chemical process industry to produce an intermediate or final product. These processes are employed to separate liquids from liquids as well as liquids from solids. From individual components to complete separation systems, De Dietrich Process Systems has the necessary equipment and knowledge to assist you with your separation needs.

Distillation is the operation whereby the vaporization of a liquid mixture yields a vapor phase containing more than one component, and it is desired to recover one or more of these components in a pure state.  Distillation as such is a major unit operation in the chemical processing industry for the purification or separation of liquid mixtures. Distillation in practical operations can be effected on either a continuous or a batch mode of operation. Columns which are packed or fitted with trays provide several theoretical stages of separation. De Dietrich Process Systems offers a complete range of equipment and systems suitable for rigorous distillation processes.

Columns

Distillation columns are one of the most commonly used thermal separation units. Their operation is based on the difference in boiling temperatures of the liquid mixture components, and on recycling counter-current gas-liquid flow. The temperature distribution up the column results in different mixture compositions at different heights.

Evaporators

In the field of thermal separation technology, evaporation plants are widely used for concentration of liquids in the form of solutions, suspensions, and emulsions. Typical evaporator applications include product concentration, dryer feed pre-concentration, volume reduction, water/solvent recovery, and crystallization.
